BOSTON –Boston Celtics reserve guard Von Wafer had no idea that it had happened, but when he found out was elated.

Wafer, who was playing on a nonguaranteed contract that he signed in August, had his contract extended until the end of the season Wednesday afternoon, but he had no idea that it happened until informed of the move by a reporter prior to Wednesday’s game.

Regardless of the method of delivery, it was good news for the guard who is averaging 2.7 points and 6.2 minutes per game, though those numbers don’t do him justice.

Wafer, who is starting to draw positive reviews for his defense, has had his moments this season, such as when he scored 10 points against the Minnesota Timberwolves Monday night.

“He earned the right to be here,” coach Doc Rivers said. “He’s contributed to our wins even before he was playing and he’s really been working everyday to become a better player in practice. He’s been good.”

Rivers also said that guard Delonte West, who is recovering from a broken wrist, also had his contract guaranteed.

Guard Ray Allen feels that that Wafer has the talent to become one of the better shooters in the league and is impressed by the patience that he has displayed while waiting to get his opportunities on the court.

“Sometimes you see these young guys get disturbed waiting on the sideline, I always tell him, ‘You have enough talent to play, you just have to stay patient and when you get out there be patient,’” Allen said.

Garnett starts basketball activities: Forward Kevin Garnett, who is currently out with a right calf strain, resumed basketball activities Wednesday morning.

After his teammates were done on the floor at the Celtics practice facility, Garnett came out and took part in what is described as a light shooting drill.

Rivers says that Garnett is still on pace to return after missing two weeks of action, which would put him back on the court towards the end of next week.

Garnett suffered the strain while going up for a dunk against Detroit last Wednesday. An MRI confirmed the strain.

Still peeved: When speaking about San Antonio forward DeJuan Blair, who slipped to the second round of the draft due to medical concerns, it brought up some old memories for Rivers.

Rivers was selected in the second round of the 1983 draft and 27 years later he can still name each and every guard who was picked ahead of him.

“I was [No.] 31. I remember all the guys that freaking went in front of me. They all [stink],” Rivers said with a laugh. “I can give you names, but I won’t. You always remember. The draft is just one day number and your career is what you decide to make of it.”

Rivers made a good career for himself, averaging 10.6 points and 5.7 assists before retiring following the 1995-96 season.
